If a small sample adapter is selected, the measurement range will be reduced by 6 times under the corresponding specifications), ultra-low viscosity adapter (rotor 0), micro printer, dedicated viscosity constant temperature water bath, DV data acquisition and programmable analysis software, standard oil, remote control.

Technical advantages:

It can be used standalone or connected to a micro printer and computer for data collection.

By applying our company's invention patent, we have overcome the drawback of domestic instruments that can only sample once per rotation, and achieved the technology of multiple sampling per rotation.

The high subdivision drive stepper motor rotates with accurate and stable speed, and the change in AC voltage frequency does not affect the accuracy of viscosity measurement.

For thixotropic non Newtonian liquids, the timing function of the instrument can ensure obtaining good consistency data.

Featuring humanized and personalized design, with 7500 continuously adjustable shear rates. It can synchronously display shear stress, shear rate, speed, viscosity, time, temperature, and the maximum measurable viscosity value of the rotor at the current speed.

Choosing DVLoad software allows users to download custom measurement programs to the instrument for fully computerized automation, or choose DV data acquisition and programmable analysis software for data acquisition and programmable analysis.

The full range and linearity of each gear of the instrument are calibrated through a PC interface, and its measuring performance and functions have reached the advanced level of the same type abroad.

Build an RTD temperature probe to monitor sample temperature in real-time, with an accuracy of 0.1 ℃ and a temperature range of 0-100 ℃.

Different standard rotors can be selected as needed

Adopting a 16 bit microcomputer processor as the core, the stepper motor is driven with high subdivision and digital LCD with blue backlight function.

According to the needs, standard materials from the metrology bureau can be selected to calibrate the viscometer, so that the inspection level is in line with international standards.
